ADJU$TABLE CONVEYER SUPPORT FOR CONVEYERS.

Application filed June 7, 1922.

To all whom it may concern.

Be it known that we, ARTHUR J. HARTLEY and .VILLIAM HJJIE, citizens of the United States of America, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Adjustable Conveyer Supports for (loiiveyers, of which the following is a specification.

Qur invention reluates to an adjustable conveyer support for a conveyer.

The invention has special application to an adjustable thrust resisting member, interposed between a normal support or framing part of a thresher and the free end of a supporting bar, pivotally attached to a conveyer and to its relationing with respect to said support and bar, whereby said adjustable member is rendered active, through the movement of the conveyer, for effecting stop positioning of said conveyer.

The invention consists in the detailed fashioning of a rockable member,the relationing of the same to its support anolto a supporting bar for a feeder, whereby longitudinal extension or retraction of the feeder bar will cause the rockable member to be shifted to different normal supporting positions against the thrust of said bar and to means for effecting inter-lock between the rockable member and the bar in non-normal positioning of the conveyor, whereby thrust action of the bar may cause the rockable member to be moved upon its support to a normal supporting position.

The invention also includes detailed structures essential to the relationing of the rockable member to its support andto the feeder supporting bar and to general combinations inclusive of the feeder and its connection with the thresher or feeder framing members.

Referring to the drawings:

Figure 1, is a side elevation showing a threshing machine and feeder parts and particularly showing the relationing of a conveyer thereto.

Figure 2, is a detailed view showing ,in side elevation parts serviceable for supporting a conveyer and indicating severalpositionings of said supporting parts.

Figure 3, shows in front elevation the same supporting par'tsjthat are shown in Figure 2. i

the framing parts of the feeder.

Serial No. 566,579.

Figure 4, is a detailed view of a rockab-le member and support."v

The present invention isdesigned as an improvement on. old methods for adjusting and supporting a conveyer indifferent positions. Heretofore the common and mostimproved method, in'use, was and is, that of utilizing relatively extensible or retractable screw members positioned beneath the con: veyer and requiring the application of a Wrench to' actuate the conveyer adjusting members.

In practice it has been found that two positions of the feeder are all that need be established to meet all the practical requirements in connection with the use of the conveyer as a receiving and carrying element in'unloading grain from vehicles orgrain stacks.

It is our aim to simplify former conveyer supporting methods to the end of reducing costand saving time.

The broad thought involved here has ref erence to the manual lifting of the conveyer to a normal high position and t0 the capability of utilizing gravity force under.

manual control to effect a lowering to a normal low posltion as distinguished from the screw acting methods hereinbefore mentioned. There is necessarily included, of

course, in conjunction with. the broad thought, certain means functioning inconnection withthe moving conveyen which is herein shown to include a supporting bar, framing members, associated with the thresher body, and means actuated throughthe movement of the conveyer to establish certain supporting. and locked positions.

It will be seen that through our improvement the minimum of manual force is required, as such force is designed to be applied at the extreme outer end of the feeder andfurthermore, it is to the convenience of the operator or workman that' such force maybe so applied. j

In the drawings, A and.B refer to thresher and feeder parts. 10, is a conveyer having a pivotal connection as at 11, with 12, is a bar, the same being. pivoted as at 13, to the body of the feeder. 14, is afiangedframing support. 15, is a plate'applied to the porti n f f am g member '14, the same be ing fashioned at its lower portion with flanged seat 16, for the entry and seating of a cross framing tubular member 17, the latter being held in its position in said seat by means of rod 18, said rod also acting in conjunction with nut 19, and said tubular member to secure the lower end of plate 15 to the framing member. The upper end of plate 15 secured to the framing member by means of short bolt 20 and nut 21. Plate 15 is also fashioned with a seat 22. 23 refers to a longitudinally bored body portion of a rockable member and 2 L25 respectively to laterally projecting wing members attached thereto. 26 is a seating boss member fashioned upon the body member 23 and wing member 24 and is adapted to be supported in seat 22 of plate member 15. particularly to the wing members of the rockable member (see Figure 2) 27 are rearward extensions from the main wing portions 24t'25 and are slotted as at 28 to facilitate a seating support for the rear end of supporting bar 12. The rear end of bar 12 is transversely perforated and affords a seat for bolt 29, which bolt in practice is seated within slots 28 of the wing members.

Attention is called to Figure 2, wherein the operative result, with respect to differences in positioning of the rockable meinher, is shown, resulting, from th raising or lowering of the feeder. In solid lines in this figure the feeder is being supported in its normal lower-most position, wherein it appearsthat the rockable member has been thrust rearwardly, through the movement of bar 12, until bolt 29 is in contact with the extreme rear end of slot 28 and the bar is in contact with the main body portion 28 of the rockable member,- hereby effecting a complete stop against further lowering movement of the feeder. The bro-' ken line position of bar 1.2, shows a relative positioning of said bar and rockable member when the conveyor is in its elevated supporting position, wherein it appears that bolt 29 rests in the extreme forward portion of slot 28 and in a position below a line through the centers of the bolt and the sup port for the rockable member, whereby thrust action of bar 12, will cause the contactportions 30, of wing members 24.-25, to be lodged against the cross-frame sleeve member 17, thereby supporting the conveyer in its normal elevated position.

In order that gravity force may be brought into play, in the lowering movement of the conveyer, to effect rearward rocking action of the rockable member, it is necessary to first relieve said rockable mcmberfrom its locked condition shown, in broken line position; therefore we have provided the pawl member 31, pivotally secured upon bolt 29, and the arcuately' fashioned laterally extending pawl seat 32,

Referring 7 on wing member 25,,and attention iscalled to the relationing of said parts as shown in broken, as well as in dotted lines, in Figure 2, wherein it will be made to appear that upon raising the conveyor above its normal elevated position, as shown in broken lines, to its position as shown in dotted lines, the resultant rearward projection of bar 12, will cause bolt 29, to be drawn forwardly upon the incline of the wall of slot 28 to approximately the maximum forward extremity of said slot, thereby carrying pawl 31 into the seating position, shown in dotted lines in said figure, in connection with arcuate pawl seat 32. and disposing bolt 29, in an off-center relatioinwit-h respect to the centering of the rockable member, and the bolt, thereby permitting thrust action of bar 12 to move the rockab'le member rearwardly, such thrust action of bar be ing possible because of the inter-lock effected between the pawl member and the pawl seat. In the rearward movement of the rockable member, resulting from the thrust of bar 12, at the lowering of the feeder. it will be noted that bolt 29 is finally lodged at the extreme end of slot 28, whereas, in the locked position, of. the pawl andpawl seat, it will be seen that said bolt is positioned some distance from the rear end of said slot. This clearance space or extra length of slot is provided so that the pawl may )e raised high enough to pass over the upturnel edge of the arcuate pawl seat 32, in order to be lodged in said seat and then again this clearance space is necessary to provide for release of the pawl from its seat when the conveyer has reached its normal low supporting position, that it may be free and inactive when the rocka-ble member is again shifted in raising the conveyer to its normal elevatedposition.

The foregoing descriptiomit is thought, has so clearly defined the operation of the device here in question that it, is not thought necessary to further define the detailed operation of the device.

The inventionherein is broadly directed to means associated with a pivoted conveyer and a supporting rod, actuated by the raising and lowering of the conveyer for positioning such means to effect stop and release action, to the end of effecting plural positioning of said elevator by the simple application of manual force, applied preferably. at the extreme outer end of said'con veyer. We have here shown the means to accomplish the end above noted, but we do not confine ourselves to the specific means herein shown, but claim all means to the same end that fall legitimately within the principle herein exemplified.
